中美通过静载试验确定单桩极限承载力的实践分析
|
摘要
静载试验是确定单桩极限承载力准确性较高的重要方法之一,中美主要规范对于通过静载试验确定单桩极限承载力的方法和规定不尽相同。总结了中美静载试验及单桩极限承载力取值方法等方面的异同点,介绍了印尼某电厂静载试验概况及结果,比较分析了按中美两国规范确定单桩极限承载力的成果,并对工程实践提出了取值建议。
The static load test is one of the important methods to determine the ultimate axial compressive capacity of a single pile with a relative high accuracy. The static loading test procedures for the axial compressive capacity of a single pile in US and Chinese code are different. This paper summarizes the similarities and differences between the static loading test procedures and methods to determine the ultimate axial capacity of single piles. This paper also compares the static loading test results on piles in a power plant in Indonesia using both US and Chinese test procedures.
